2018-03-29qede: Do not drop rx-checksum invalidated packets.Manish Chopra1-8/+2
Today, driver drops received packets which are indicated as invalid checksum by the device. Instead of dropping such packets, pass them to the stack with CHECKSUM_NONE indication in skb.

2018-03-29perf/x86/pt, coresight: Clean up address filter structureAlexander Shishkin4-49/+63
This is a cosmetic patch that deals with the address filter structure's ambiguous fields 'filter' and 'range'. The former stands to mean that the filter's *action* should be to filter the traces to its address range if it's set or stop tracing if it's unset. This is confusing and hard on the eyes, so this patch replaces it with 'action' enum. The 'range' field is completely redundant (meaning that the filter is an address range as opposed to a single address trigger), as we can use zero size to mean the same thing.

2018-03-29lockdep: Make the lock debug output more usefulTetsuo Handa1-2/+2
The lock debug output in print_lock() has a few shortcomings: - It prints the hlock->acquire_ip field in %px and %pS format. That's redundant information. - It lacks information about the lock object itself. The lock class is not helpful to identify a particular instance of a lock. Change the output so it prints: - hlock->instance to allow identification of a particular lock instance. - only the %pS format of hlock->ip_acquire which is sufficient to decode the actual code line with faddr2line. The resulting output is: 3 locks held by a.out/31106: #0: 00000000b0f753ba (&mm->mmap_sem){++++}, at: copy_process.part.41+0x10d5/0x1fe0 #1: 00000000ef64d539 (&mm->mmap_sem/1){+.+.}, at: copy_process.part.41+0x10fe/0x1fe0 #2: 00000000b41a282e (&mapping->i_mmap_rwsem){++++}, at: copy_process.part.41+0x12f2/0x1fe0 [ tglx: Massaged changelog ] Signed-off-by: Tetsuo Handa <[email protected]> Signed-off-by: Thomas Gleixner <[email protected]> Acked-by: Michal Hocko <[email protected]> Acked-by: David Rientjes <[email protected]> Acked-by: Peter Zijlstra <[email protected]> Cc: [email protected] Cc: Borislav Petkov <[email protected]> Link: https://lkml.kernel.org/r/[email protected]

As of the start of 2018, I am no longer paid to support the core 32-bit ARM architecture code. This means that this code is no longer commercially supported, and is now only supported through voluntary effort. I will continue to merge patches as and when able, but this will be at a lower priority than before (which means a longer latency.) I have also be scaled back the amount of time spent reading email, so email that is intended for my attention needs to make itself plainly obvious, or I will miss it. In an attempt to reduce the amount of email Cc'd to me, exclude arch/arm/boot/dts from the maintainers patterns, but add entries for the SolidRun platforms I look after.

This patch fixes commit 5f48f0bd4e36 ("mm, page_owner: skip unnecessary stack_trace entries").

All the root caches are linked into slab_root_caches which was introduced by the commit 510ded33e075 ("slab: implement slab_root_caches list") but it missed to add the SLAB's kmem_cache. While experimenting with opt-in/opt-out kmem accounting, I noticed system crashes due to NULL dereference inside cache_from_memcg_idx() while deferencing kmem_cache.memcg_params.memcg_caches. The upstream clean kernel will not see these crashes but SLAB should be consistent with SLUB which does linked its boot caches (kmem_cache_node and kmem_cache) into slab_root_caches.

2018-03-28RDMA/ucma: Introduce safer rdma_addr_size() variantsRoland Dreier3-17/+35
There are several places in the ucma ABI where userspace can pass in a sockaddr but set the address family to AF_IB. When that happens, rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6, and the ucma kernel code might end up copying past the end of a buffer not sized for a struct sockaddr_ib. Fix this by introducing new variants int rdma_addr_size_in6(struct sockaddr_in6 *addr); int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr); that are type-safe for the types used in the ucma ABI and return 0 if the size computed is bigger than the size of the type passed in. We can use these new variants to check what size userspace has passed in before copying any addresses.

2018-03-28locking/rtmutex: Handle non enqueued waiters gracefully in remove_waiter()Peter Zijlstra2-7/+7
In -RT task_blocks_on_rt_mutex() may return with -EAGAIN due to (->pi_blocked_on == PI_WAKEUP_INPROGRESS) before it added itself as a waiter. In such a case remove_waiter() must not be called because without a waiter it will trigger the BUG_ON() statement. This was initially reported by Yimin Deng. Thomas Gleixner fixed it then with an explicit check for waiters before calling remove_waiter(). Instead of an explicit NULL check before calling rt_mutex_top_waiter() make the function return NULL if there are no waiters. With that fixed the now pointless NULL check is removed from rt_mutex_slowlock().

2018-03-28Revert "x86/mce/AMD: Collect error info even if valid bits are not set"Yazen Ghannam1-14/+0
This reverts commit 4b1e84276a6172980c5bf39aa091ba13e90d6dad. Software uses the valid bits to decide if the values can be used for further processing or other actions. So setting the valid bits will have software act on values that it shouldn't be acting on. The recommendation to save all the register values does not mean that the values are always valid.

2018-03-28x86/boot: Fix SEV boot failure from change to __PHYSICAL_MASK_SHIFTTom Lendacky3-18/+15
In arch/x86/boot/compressed/kaslr_64.c, CONFIG_AMD_MEM_ENCRYPT support was initially #undef'd to support SME with minimal effort. When support for SEV was added, the #undef remained and some minimal support for setting the encryption bit was added for building identity mapped pagetable entries. Commit b83ce5ee9147 ("x86/mm/64: Make __PHYSICAL_MASK_SHIFT always 52") changed __PHYSICAL_MASK_SHIFT from 46 to 52 in support of 5-level paging. This change resulted in SEV guests failing to boot because the encryption bit was no longer being automatically masked out. The compressed boot path now requires sme_me_mask to be defined in order for the pagetable functions, such as pud_present(), to properly mask out the encryption bit (currently bit 47) when evaluating pagetable entries. Add an sme_me_mask variable in arch/x86/boot/compressed/mem_encrypt.S, which is set when SEV is active, delete the #undef CONFIG_AMD_MEM_ENCRYPT from arch/x86/boot/compressed/kaslr_64.c and use sme_me_mask when building the identify mapped pagetable entries.

2018-03-27qede: Fix barrier usage after tx doorbell write.Manish Chopra1-6/+4
Since commit c5ad119fb6c09b0297446be05bd66602fa564758 ("net: sched: pfifo_fast use skb_array") driver is exposed to an issue where it is hitting NULL skbs while handling TX completions. Driver uses mmiowb() to flush the writes to the doorbell bar which is a write-combined bar, however on x86 mmiowb() does not flush the write combined buffer. This patch fixes this problem by replacing mmiowb() with wmb() after the write combined doorbell write so that writes are flushed and synchronized from more than one processor.
